Killing time, parks, pools and bulldogs can be defined as a self-cognitive documentary, produced through an anthropological-multimodal experience where the creative process represents a possibility of emancipation, capable of involving all participants in the production of knowledge. It is the result of the research process in the educational field at the "Renzo Pezzani" middle school in Corvetto, Milan.

The film passes through memories, places and times near and far, alternating with fantasies, desires, fears. It tells of a city that leaves no room for children, of games on the escalators of a shopping center, of drug dealers, of fights, interspersed with idyllic seaside landscapes, children's swimming pools and seas that submerge Christmas markets. In their free moments they play to kill time, the empty opportunity of idleness, potentially full of creativity. They nicknamed themselves The Paper Boys ( I ragazzi di carta) because like paper they immediately catch fire but are also resistant.
